Abstract :
Wavelet image compression offers several advantages over existing methods such as the DCT adopted in the JPEG standard, and has now been adopted by MPEG-4. This paper presents some wavelet codec implementation architectures obtained by a joint optimization of both the algorithmic and architectural features, according to system hardware and software strategy. Results are presented which allow optimization of system performance either for dedicated ASIC design or for embedded software implementation based on available execution speed and cache memory performance.
